When I go to lock the car from the drivers side, sometimes only the passenger door locks with the drivers and sometimes only the drivers door locks. I recently did a valve adjustment and was constantly moving the vacuum lines out of the way. Did I disrupt some vacuum door lock control?????

Most likely, yes. Check the two yellow lines that connect to the the little yellow check valve near the firewall, next to the fuse box.

You probably pulled a plastic vacuum line out of one of the rubber tees, causing a vacuum leak. You can confirm this by locking the car with the door button while the engine is running and you are inside. If the locks all work, the presence of a leak is pretty well confirmed. Look over the collection of hoses carefully; see if you can find one that is disconnected.
